Apparently my understanding of Cogl pixel formats, or at least their use, was somewhat shaky. Un-invert the inversion of the DRM FourCC -> Cogl pixel format mapping when creating dmabufs from clients, fixing inverted channel ordering seen from GL clients, e.g. gold highlights in gtk4-demo when using the GSK GL backend when they should be blue. https://bugzilla.gnome.org/show_bug.cgi?id=786677
